SPECIFICATION forming part of Letters Patent N 0. 792,627, dated J une 20, 1905.

Application iiled April 15, 1904. Serial No. 203,261.

T0 all whom, it 777//1/7/ concern:

Be it known that I, ROBERT STURGES, a citizen of the United States, residing at Vatervliet, county of Albany, and State of New York, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Figure 1 of the drawings is an end elevation of my improved gas-stove or heater. Fig. 2 is a central vertical longitudinal section of the same, taken on the broken line 2 2 in Fig. 1. Fig. 3 is a vertical cross-section of the gas-burner pipe and its guide-trough, taken on the broken line 3 3 in Fig. 2.

The object of my invention is to secure greater economy, efficiency, and safety in the use of gas for heating purposes.

Referring to the drawings, wherein the invention is shown in its preferred form, l represents the base-casting, which is supported on legs 2 and is provided with a central aperture 3 and numerous small apertures 4, adapted to permit the escape of heated gases.

A casing' rests upon the base, inclosing the central aperture 3, and is hinged to the base at 6, being adapted to be swung upon said hinge toward and from the base. The casing 5 is preferably closed at its sides and top, except for damper-apertures 7 in one of its sides near the top, which are adapted to be closed by a movable valve or damper in the form of an apertured slide-plate S, movable in slideways 9. By imparting to the damper slide movements along its slideways either the damper-apertures 1 0 can be brought opposite the apertures 7 in the wall of the casing to open the damper and give vent to the upper end of the casing-chamber or the closed portions of the damper-plate can be brought opposite the casing-wall apertures 7 to close the same.

The gas-burner comprises a pipe 11, provided with closely-arranged nipples 12, projecting upwardly therefrom, which pipe is slidably supported in a guide-trough 13, mounted upon the base-casting, one end of said trough resting in a spring-socket 14 and its other end being supported by the burnerpipe, ywhich it partly embraces. The nipples l2 project upwardly through the open top of the trough, which forms a slot 16, along which the nipples travel when slide movement is imparted to the burner-pipe. The burner-pipe extends out through an aperture in the base at 15, which is of a size and, form adapted to permit the pipe and its nipples to slide kfreely therethrough. The burnerpipe can thus be drawn out partly from the base to expose one or more of the nipples when it is desired to light the stove, and

when one or more of the nipples are thus lighted and the burner slid back fully Within the base the flame from the lighted nipple or nipples will travel from nipple to nipple until all the nipples are lighted. The base is provided with a bottom 17, which is perforated to afford a supply of air for the burner.

Mounted upon the base, just above the burner, is a hood 19, which is tapered upwardly and provided in its apex with an escape-opening 20 for the heated gases arising from the burner through said hood. The -hood is provided With a base-fiange 21, which extends to the sidewalls of the base, forming a bottom-closure for the space outside of the upwardly-projecting body of the hood and serving to prevent the escape of the heated gases from the casing-chamber downwardly outside the hood to the burner. The hood is made to project upwardly well into the casing-chamber, and its top opening being comparatively small there is no downdraft therethrough. The burner being thus protected from downdraft operates with maximum efiiciency.

l l/Vhen the damper is closed and the burner is in operation, the heated gases from the burner rise withgreat velocity through the hood and are delivered through the top opening in the hood into a comparatively large body of less highly heated gas in the upper IOC
